The
new
lines,
already
delayed
by
a
year,
are
widely
expected
to
help
ease
the
bottleneck
in
transmission
of
wind
power.
China
is
the
first
country
to
develop
UHV
transmission
lines
on
a
commercial
basis,
driven
by
the
need
to
feed
its
power-hungry
cities
in
the
east
with
energy
largely
produced
in
remote
regions
in
the
west.
UHV
power
lines
allow
for
a
huge
quantity
of
electricity
to
be
transmitted
down
a
single
line
and,
when
in
direct
current
(DC),
over
vast
distances
with
minimal
power
losses.
